Styling the custom user registration forms in django
I have created custom user registration. I would like to style them using input placeholders and class names. models.py from django.contrib.auth.models import AbstractUser from django.db import models class CustomUser(AbstractUser): username=models.CharField(max_length=30, unique=True) email=models.EmailField() password1=models.CharField(max_length=30) highestQualification=models.CharField(max_length=50) def __str__(self): return self.email This is how I want to style my signup.html with the input fields styling and placeholders. <!DOCTYPE html> <html> <head> <style> .container { position: relative; } input{ padding: 12px; border: 1px solid gray; } input:hover{ opacity: 1; } </style> </head> <body> <div class="container"> <form method="post"> <div class="row"> <div class="col"> <input type="text" name="username" placeholder="Username" required> <input type="email" name="email" placeholder="Email" required> <input type="password" name="password1" placeholder="Password" required> <input type="text" name="highestQualification" placeholder="Highest qualification" required> <input type="submit" value="Sign up"> </div> </div> </form> </div> </body> </html> The basic version of the signup form (without styling) looks like this. signup.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> {% block title %}Sign Up{% endblock %} {% block content %} <h2>Sign up</h2> <form method="post"> {% csrf_token %} {{ form.as_p }} <button type="submit">Sign up</button> </form> {% endblock %} </head> <body> </body> </html> Wanted to know where to mention the styling class names and placeholders of the input field. -
Multiple render in 1 function in views.py Django?
I am very new to Django... Using submit button i want to run a python file in background and display content on next page... But my python file takes some time to take out the result so in between i wanted to put a loading html page in between.... I have written some code which correctlty runs the python file but i am not able to incorporate the loading page in between... Take a look at my function in views.py def submit(request): info = request.POST['info'] print('value is ', info) filename = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" #result = run(['python', filename, info], stdout= PIPE ) return render_to_response("loading.html") run(['python', filename, info], stdout= PIPE ) return render(request, 'python_output.html', context) ACTUAL RESULT: return render_to_response("loading.html") works but then the control does not shifts to run command... I want to run the loading html page and run the python file in background and when python file run finishes it should move to python _output.html page where output is displayed... Expected: Loading page should work and after that control should shift to run command and then it should go to python_output.html page.../ -

Django Simple History - History Diffing
So I'm using django-simple-history for one of my projects. I'm using it on one of the models called "Address" to show the history of the records. I've created a DetailView to show the information about the address and added context['history'] to show changes of the record. This works all fine. I would be interested in what field changed, and I read the following; History Diffing So I somehow need to loop through all the fields from the last two records and find the field which has changed...

Django startapp workflow with docker
I am confused with how to work with Django apps (create/using) when using Docker. Some of the tutorials suggest using command startapp after starting the web docker container (I'm using docker-compose to up the containers). But since the files are created inside that container, how do I go about adding code to that from my local dev machine? and moreover, this does not seem right to create apps like this to edit code... I've been using this following structure as is so far which starts up the container and works fine.
